Bug ID: 24064 Summary: bfd/warning.m4 warning detection broken when !defined(__GNUC__) Product: binutils Version: 2.32 (HEAD) Status: UNCONFIRMED Severity: normal Priority: P2 Component: binutils Assignee: unassigned at sourceware dot org Reporter: andrew at ishiboo dot com Target Milestone: --- Created attachment 11511 --> https://sourceware.org/bugzilla/attachment.cgi?id=11511&action=edit Adjust bfd/warning.m4 egrep patterns `bfd/warning.m4` performs `egrep` checks against the preprocessor output of `__GNUC__`: > # Set WARN_WRITE_STRINGS if the compiler supports -Wwrite-strings. > WARN_WRITE_STRINGS="" > AC_EGREP_CPP([^[0-3]$],[__GNUC__],,WARN_WRITE_STRINGS="-Wwrite-strings") This will incorrectly enable `-Wwrite-strings` if a non-GNU compiler is being used and `__GNUC__` is not defined by the preprocessor. The pattern for these checks needs to be adjusted to also treat `__GNUC__` in the output as "unsupported". This breaks when Oracle Studio compiler is used, as `-W` is not a warning switch, and it errors: > $ cc -Wwrite-strings > cc: -W option with unknown program write-strings -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
